Serial No. 324,348.

My invention relates to improvements in strip finishing machines. a

The object of my invention is to provide an improved guide for a strip finishing ma chine, whereby thestrips of flooring are guided more accurately in their rapid passage through the machine and providing means whereby one of the guides can be swung outwardly and upwardly forremov- 1o ing the strips in the event they become jammed for any reason whatever.

Another object of my invent-ion is to provide an improved guide for strip finishing machines in which an adjustable means is provided for the rigid or lower guide so that it can be adjusted vertically in respect to the upper guide to allowstrips of flooring of different width to pass through the machine or take up any wearof the guides.

A further object of my invention is to provide a simple, cheap and effective arrangement of the movable upper guide and a vertically adjustable stationary lower guide and said arrangement having certain details of structure and combination of parts hereinafter more fully set forth.

Figure 22 is an edge view of Figure 21. Referring now to the drawings, 1 repre sents the base of an ordinary strip finishing machine, and upon which is secured, by means of bolts 2 and 3, the upwardly extending plate or frame 4 having at its upper end the en'- larged' head portion5 having a rectangular groove 6 extending from end to end thereof. The head portion 5 at one side is provided with an outwardly extending arm 7 having a horizontallyarranged opening 8 therein, adjacent the head, and the outer end of said arm having a vertically disposed screw threaded opening 9 therethrough the purpose of which will be hereinafter more fully described.

Mounted on the head portion ,5 of the plate or frame 4 is an upwardly extending plate 10 having outwardly extending earsll and 12 at its lowerfend and provided with openings through which bolts 13 and14 pass and said bolts screwed into the-openings in the ears 15 and 16 carried by the outer face of the head 5 of the plate or frame 4, whereby the member 10 is rigidly supported by the member 4 in the position shown in Figure 1 of the drawings.

' Within the rectangular recess 6 of the head 5 is the lower g ide member 1 B1 a r d our on each side thereof within the recess 6 is the guide member holding plate 19 which abuts against the vertical faces of the guide and hold it in its vertical position. The plate 19 is locked in posizion by the blocks 20, as clearly shown in Figure 7 of the drawings. Mounted within the horizontal opening 8 of the arm 7 is a pin or shaft 21 carried by a lever 22 intermediate its ends and whereby said lever is intermediately pivoted on the arm 7. The inner end 23 of the lever 22 extends under the guide member 17 and serves as a support for the same, and a number of levers are provided for supporting the guide at several points. The opposite end of the lever 22 extends out over the opening 9 in the arm 7 and is provided with a bolt 24 adapted to screw into the threaded opening 9 of the arm 7. By this structure it will be seen that the lower guide member 17 may be raised or lowered in respect to the upper guide member by turning the bolt 24, as clearly shown in Figure 1 of the drawings.

The upper end of the plate 10, as shown in Figures 1 and 40f the drawings, is provided with an outwardly extending pin 25 which extends in a horizontal line and passes through an elongated opening 26 in the operating lever 27. The lever 27 extends in an oblique direction and passes between the arms 28, carried by the upper end of the member 10 and is guided thereby. The lever 27 has a reduced rounded portion 29, and surrounding the same is a coil spring 30 which bears against a block 31 sliding on the reduced portion of the lever, whereby said block frictionally engagesthe arms 28 and holds the lever in its adjusted position. The member 10 on its inner faceis provided with a boss 32 throughwhich passeswaset screw 33' adapted to engage the enlarged portion of the lever 27, as clearly shown in Figure 1 of the drawings, for limiting the movement of the lever.

The lower end of the lever 27, below'the pivot '25,extends in an oblique direction and is pro vided with the laterally turned end 34 adapted to enter the opening 35 in the block 36. The block 36 ispivotally mounted at 37 upon the pin 38 carried by the plate 10. The block 36 is provided with a downwardly extending arm 39 having an opening 40'therein. into which is screwed a bolt 41, said bolt is also screwed into the upper guide member 42, whereby this guide member is pivotally supported by the block 36. A number of blocks 36 are provided whereby the guide member is supportedat several points.

The guide member 42', as clearly shown in Figure 20' of the drawings, is made in two sections 43 and 44 secured together in any desired manner, as this has been found to be the most practical way of making the same.

Arranged beside the guide member 42: is a plate 45 which serves as a stop and brace for the guide member 42, limiting its movement in one direction but allowing it to be swung outwardly in the opposite direction.

From the foregoing description it will be seen that should a strip of flooring become jammed in the machine between the upper guide member 42 and the lower guide member 17, the lever 27 is moved, causing the laterally turned end 34 to move the block 36 on its pivot 37 and swing the upper guide mem ber outwardly and upwardly so that the strip of flooring can be removed from the machine. In this movement of the lever, the

spring 30 is holding the block 31 against the plates 28' and when the lever is released the lever Will be held in its position so that the upper guide member isheld in its upward position. The spring 30 also holds the lever in its position so that the upper guide member is held in its vertical operative position but when undue pressure is exerted thereon it may swing upwardly and outwardly.

The plate 10, as shown in Figure 4 of the drawings, is made so that the lever can be mounted to operate from either the right or left side of the machine. stood that there is a block 36 and a lever 27 and the other end of the upper guide member 42 operated in precisely the same manner as the lever 27, shown in Figure 1 of the drawings.

\Vhile in the specification 1 have described my invention as especially adapted to be used for finishing strips of flooring, it is, of course, understood that the same can be used in connection with any guiding means for guiding strips of lumber of any kind.
